2. Starting operations
- The pressure switch should be installed and operated only by authorized personel.
- Cover and bottom of the device form a function unit. Exchanging the parts can cause measuring errors
or malfunctionning. For wall mounting remove the four front cover screws and the front cover. Then
fasten the device with four screws to the wall and finally remount the front cover. To damp strong
vibrations shock mounts must be used.
- Connect the sensor to the (3-pin + PE) cube plug at the bottom side of the UAD 3 - V3.
- The electrical connection (supply, analog output switching contacts) must be carried out according to
the connection tables depicted on the top of the device by removing the cover cap and insert the cable
through the cable gland PG 13,5. If required, additional cable glands can be installed in the cover cap
by breaking out the perforated cavities.
- The electrical connection must be carried out in accordance with the VDE 0100 regulations. In order to
ensure trouble-free operation it is essential to connect the protective lead.
- If inductive loads (magnets, contactors, etc.) are connected to the switch relays, suitable protective
devices (varistors etc.) must be provided.
